Angel Music Box

My daughter Annie has a music box, her mother made from wood for her. Yet it plays only one single song.
She likes it very much and keep on asking me if it could play some other songs.

So I write this simple app for her. :)

Touch and move the black disk to play songs.
Also you can tap the "A" button, so it will play automatically.

Using left arrow and right arrow to switch between different songs.
Songs included:
Jingle Bell
ABC Song
Fur Elise
Silent Night
Auld Lang Syne
Bolero
Two Tigers
Snail and Oriole
